This experiment was conducted to clarify the antitussive effect of Fritillaria unibracteata Hsiao et K. C. Hsia. The antitussive effect in ethanol (75, 50, 30%) extracts from F. unibracteata was relatively high. The ethanol extracts of 20, 40 mg/kg concentrations were especially good antitussive effect. The ethanol extracts of F. unibracteata showed lower antitussive activities of 20~30% than sodium chloride injection used as a blank space control.

Antimicrobial activities of methanol, ethanol, water, and $CH_2Cl_2$ extracts from Fritillaria unibracteata Hsiao et K.C. Hsia and F. ussuriensis Maxim. were investigated by disk-agar diffusion method. The result showed comparatively strong antimicrobial activity against several microorganisms. The extracts from F. unibracteata and F. ussuriensis dosedependently increased the activity. However, water and $CH_2Cl_2$ extracts showed no antimicrobial activity against 7 microorganisms. Especially, against the most sensitive microorganism Staphylococcus epidermidis, methanol extracts at highest concentration of 20 mg/mL exhibited the largest clear zone on plate by 6-12 mm and ethanol extracts on plate by 6-10 mm.
